Referring first to said Figs. 1, 2, 3 and 4, the numeral 31 denotes the body of a passenger motor vehicle, from whose front axle 37 and rear axles 20 the usual carrying-Wheels have been removed in order to substitute therefor my sleigh attachments.

Runners 32 of a simple construction are used at the front of said vehicle, each having a hollow bearing sleeve 36 rigidly mounted on a standard 33 braced at'front and rear by the brace-bars 34 and 35.

A somewhat similar pair of runners l are mounted on the rear axles 20 pivotally also,

an intermediate s outer '19,]. and 24 re .d 'ks i nr he her summit als but p ace eiimsi'tly T l n memb r dentat'ed widened" cross each runner having three standards 4, 28 and 2, which are rlgldly connected together and-to the upwardly curvedfront 1 part of the runner by meanspflbrace-bars 6 and 38. As shown-in FigQ 2, said standards are arranged in pairs, and a hollow bearing 23. is mounted adjustably uponthe offset tops of thestandards by neansiof a. bolt, andlthe axle spindle terminal pivotally mounted lIIlSiLlCl bearing removably. ;Up,on ,thlea xle spindle. 20. is f xed i rfemojvably a sleeve 20 having'fthereonja.sp'rocketrpinionf26.

,Tlie YnumeralQ-S denote J pair. f ,fprbdelzof .e n.

i hee;l. aun f t l2 at their lowerends. These are similar to the single propelling member 8 shown in Fig. 5, but their upper ends are slidingly connected to and seated in diametrical holes in the relatively large crank-pins 27 which latter are pivotally mounted in said disks 24, to slide freely therethrough. The members 8 have threaded ends with terminal securing and adjusting nuts. and between an enlargement on eachmember 8 and said crank-pin 27 a coiled compression-spring is mounted on said member and engaged between the enlargement and the crank-pin. j I

A connecting-rod or pitman 17 is pivotally connected between the crank-pin on each disk 19' and the member 8 side. This connecting-rod is adjustably constructed with the two elements 17 and 14 having their abutting ends-provided with interiorly threaded sockets to receive the fa ke ii l .2 1 a atelhav ngja s haft'j rotatably mounted in t ed like disks onthe same the device has'but one propelling member 8,

and may be mounted on the driving axle of a bicycle or tricycle or the like at 20, the

disk 19 being removably fixed on the axle, with the-member part 17 terminally pivoted on the disk crankpin 18. The upper part of the member 8 is slidingly inserted in a rockable eye-bolt 10 which traverses a hori- Zontally rocking member 7 mounted on the top of the rear standard 2, the latter having a brace link 3 to the rear heel of the runner 1. Nuts 11 are placed on the threaded. terminal of the member 8 for securing same and for adjusting the tension of the coiled spring 9 which is engaged between anenlargement of the member 8 and the eye of the bolt 10. I

In this device the rotation of the driving axle 20 causes the pitman 17-14 to oscillate the propelling member 8 swingingly so as to at intervals engage the surface of ice or snow beneathand at one side ofthe' runner 1 and with a pushing movement thereagainst propelling the runner forwardly, or reversely as the case may be, the spring 9 yielding to permit of giving of the member 8 to thus disengage ground obstacles to prevent entanglement therewith orbreakage of the mechanism.

The device shownvin said Fig. 1', is operatedin a like manner, but members 8 are located on opposite sides of each runner for greater propelling power and enlarged ground contacts, with more rapidly alternated driving impulses. The sprocket-gearingshown is reducing'in speed effect with also said idler having crank-portions, the

crank on the former having'a ,diametrical bearing opening and being pivotally connected to its gear, an arm mounted slidingly in-said bearing opening and elastically adjustably connected to said crank, a sectional pitman having one section terminally pivoted to the crank on said idler, and another section terminally pivoted to said arm, and

an adjustable connecting-means between said sections. V a V 2. In combination, a sleigh runner, a shaft rotatably j ournaled on said sleigh runner and having a crank portion, said sleigh runner having to the rear of said shaft a pivoted apertured bearing member, a propeller 1 arm having a pressure foot andjhaving'its upper part slidable through the aperture of said bearing member and threaded above the latter, an adjusting-nut on said threaded part above the bearing member, a coiled compression spring on said arm engaged therewith atits lowerend and engaged at its upper end with said bearing member, and a pitman having adjustably connected sections for longitudinal adjustments pivotally connected at opposite ends with said crank portion and with saidpropeller arm above the'foot of the latter..

In testimony whereof I aflix my signature.
